Figure 4From: Application of volumetric modulated arc therapy (VMAT) in a dual-vendor environmentDose volume histograms for hypopharynx/larynx cancer. Comparison of dose volume histograms achieved with 7-field IMRT (dotted lines) and Dual Arc VMAT (solid lines). Plan quality is slightly better for VMAT, with somewhat lower dose to the parotids.Back to article page
